gstack: turn Claude Code into an AI engineering team

gstack is an open-source (MIT) set of skills for Claude Code, published by Garry Tan of Y Combinator. It gives Claude Code named roles: a CEO, an engineering manager, a designer, a reviewer, a QA lead, a security officer and a release engineer, 23 specialists in total.

Set it up

1. Install it

   You need Claude Code, Git and Bun. Then run this, or paste the longer install prompt from the README into Claude Code and let it do the rest.

   Copygit clone --single-branch --depth 1 https://github.com/garrytan/gstack.git ~/.claude/skills/gstack && cd ~/.claude/skills/gstack && ./setup

2. /office-hours

   Describe what you are building. This is the README's first step and the best place to start.

3. /plan-ceo-review

   Run it on any feature idea. The CEO role rethinks the product before any code is written.

4. /review and /qa

   /review checks a branch with changes for bugs. /qa opens a real browser and tests your staging URL.

5. /cso and /ship

   /cso runs a security audit on the repo. /ship is the release step that opens the pull request.
